One of the major strategies to control magnetism in spintronics is to utilize the coupling between electron spin and its orbital motion. The Rashba and Dresselhaus spin–orbit couplings induce magnetic textures of band electrons called spin momentum locking, which produces a spin torque by the ...

A theoretical study has been carried out on the spin-dependent electron transport in a hybrid magnetic–electric barrier nanostructure with both Rashba and Dresselhaus spin–orbit couplings, which can be experimentally realized by depositing a ferromagnetic strip and a Schottky metal strip on top of ...
SOC exists in noncentrosymmetric structures and mainly consists of two types: the Rashba effect induced by the structure inversion asymmetry (SIA) 3,4 and the Dresselhaus effectinduced by the bulk inversion asymmetry (BIA). 2">>e 2D nonpolar semiconductors lack the intrinsic Rashba effect, ...
We consider the magnetic response of a two-dimensional electron gas (2DEG) with both Rashba and Dresselhaus spin-orbit coupling to a microwave excitation. We generalize the results of [A. Shnirman and I. Martin, Europhys. Lett. 78, 27001 (2007).], where pure Rashba coupling was studied....
另外总 自旋劈裂包括 Dresselhaus 和 Rashba 项共同 的贡献,这里只考虑 了 Rashba 项,因为它直接取决 于 内建 电场. 与AllnAs/GalnAs 量子阱中的自旋 一轨道耦合 系数相 比,我们这里 计算 的结果大约 小了两个 数 量级,主要原因是 GaN 带隙 (3.44 eV) 比 GaInAs (0.816 eV) 大得 多,而根据...
We analyze the effects of in- and out-of-plane Zeeman fields on the BCS-BEC evolution of a Fermi gas with equal Rashba-Dresselhaus (ERD) spin-orbit coupling (SOC). We show that the ground state of the system involves novel gapless superfluid phases that can be distinguished with respect ...
New exact and asymptotical results for the one particle Green's function of 2D electrons with combined Rashba–Dresselhaus spin–orbit interaction in the presence of in-plane uniform magnetic field are presented. A special case that allows an exact analytical solution is also highlighted. To ...
Hidden Rashba and Dresselhaus spin splittings in centrosymmetric crystals with subunits/sectors having non-centrosymmetric symmetries (the R-2 and D-2 effects) have been predicted theoretically and then observed experimentally, but the microscopic mechanism remains unclear. Here we demonstrate that the sp...
